Abstract

The research concluded that rainfall amounts do not follow a specific spatial pattern in their changes, but rather tend towards an increase in some spatial ranges shown by the modeling maps, which may indicate that it is an extreme increase and not an actual increase. It also became clear that the stations in the north and center of the study area recorded the highest amount of rainfall during the first study period, and decreased during the second, third, fourth and fifth study periods, then it increased again during the sixth period, this is a result of climate change and the decrease in the frequency of rainy weather depressions, especially frontal ones.The high rainfall region occupy an area of %(62.6, 39.8, 53.9, 59.7, 50.0, 0.0, 73.6) for all periods respectively, Thus, the fifth period is the least occupied period in the spatial dimension, so that the high rainfall region category has completely receded. At a rate of (zero) km2 and with a deviation of (%62.6), the research also found that a region with low rainfall amounts was also subject to spatial changes, as it was found that a region with low rainfall occupies an area ratio of (12.8, 20.5, 19.8, 19.8, 17.9, 17.3, 27.1, 4.6) for all periods respectively, this means that the fifth period is the largest spatial extent for a region with low amounts of rain at (27.1) mm, while the sixth period is less extensive at (8.2-) mm.
